It's a fair question. How does an open high end chip design benefit anyone other than a competing company? How would an end user be able to verify that the chip in their hand is the same as what's in the schematics they get? Wouldn't it be cost-prohibitive for regular people to have those designs manufactured? High performance cores being opened would be nice to have but not really practical, unless I'm missing something.
